OOWL' VENTILA'IOR.

Application filed July 27,

This invention relates to an automobile body structure and particularly to the ventilation of the same. It is an object of my invention to provide a ventilator, preferably located in the cowl, and operable from within the automobile, which shall be simple,-

struction and economies of manufacture will be apparent as I proceed with the detailed description of an embodiment of the invention illustrated in the accompanying drawing in which:

Figure I is a top plan View ofa port-ion of the cowl and instrument board, with parts broken away to more clearly show my invention applied thereto.

Fig. II is a longitudinal cross sectional view taken on the line II-II of Fig. I and Fig. III is a transverse sectional view taken on the line III-III of Fig. I.

The same reference numbers refer to the same parts throughout the views.

Referring to the drawing, the cowl 5 connecting with the instrument board 6 has a ventilatingopening 7 thereln, the cowl at the edge of the opening being turned up to form a flange 8. A cover 9, shown curved to conform to the curvature of the cowl, fits over the'flanged opening 7 and has strips of packing 10, such as felt, held in place by an inner plate 11 suitably secured to and forming a part of the cover.

A member 12 having the combined function of a support forthe cover and a deflector of the air entering the cowl comprises a sheet metal plate having flanges 13 and 14 at one side for attachment to the cover and end flanges 15, each of which has an eatension or lug 16, by which the cover is pivotally mounted. Opposite each end of the plate member 12 is an angle bracket 17 secured to rying a shaft 18 upon whichthe member 12 is journalled at the lugs or extensions 16. The plate member 12 has a portion of its side edge opposite the flanges 13 and 14 cut away as at 19 and adjacent opposite sides of this ,cut away portion two angle brackets a cylindrical nut member 21.

ating rod 22- is threaded transversely through The rod the underside of the cowl and car-- 1922. Serial N0. 577,867.

20 are mounted which form bearings for trunnions formed on the opposite ends of An operthis nut member and is of suflioient length to reach through the instrument board 6, where it has a bearing in a member 23 and terminates in a milled hand wheel 2 1.

ment by a washer 25 and a pin 26 as shown in Fig. II, while its'inward movement is restricted by a coilspring 27 housed in a counter bore in the member 23 and engaging the hand wheel 24. In order to eliminate rattling of the cooperating parts, a wire spring 28 is used which engages the cover, the shaft and the nut. Inthe form illustrated, this spring has a: loop portion entail a particular structural embodiment as illustrative of my invention, I do not wish to be limited thereby, since various changes might be made therein without departing from the scope of the inventioncoveredby the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In an automobile,a cowl having a ventilating opening therein, a cover therefor, a member secured to said cover and extending into said cowl, a shaft pivotally connecting said member to saidcowl, a nut pivotally carried by said member, operating means engaging said nut and a spring engaging said cover. said shaft and said nut.

2. In an automobile, a cowl having a ventilating opening therein and a flange surrounding said opening, a cover for said opening, a member secured to said cover and extending'into said cowl, a shaft pivotally conis held from outward move- "gaging the adjacent felt strip 10, an intermediate portion encirclingthe' shaft 18 and opposite end portions engagingthe nut 21.

gaging respectively said cover and said nut.

l. In an automobile body, a cowl having a ventilating opening, a cover therefor, a

plate rigidly secured to the cover and extending longitudinally thereof and downwardly and rearwardly beneath the same,

means at opposite ends of the plate for piv- .Otfllrljflsilppflltlllg,1i] beneath the cowl, and

means oper-atively connected with the plate for opening and closing the cover.

5: In anautomobile body, a cowl having aven-tilating opening, a cover therefor, a plate substantially the length of the opening, said plate being rigidly secured to the cover and extending longitudinally thereof and downwardly beneath the same, a member rotat'ably mounted upon the plate, and an operating member for the cover having screw-threaded engagement with said rotatablymounted member.

6. In an automobile body, a cowl having a ventilating opening, a cover therefor, a plate rigidly secured to the underside of the cover and extending longitudinally thereof and downwardly beneath the same, means pivotally supporting the plate beneath the cowl, and operating means for the cover pivotally connected with the plate.

7. In an automobile body, a cowl having a ventilating opening, a cover therefor, 21 plate rigidly secured to the underside of the cover and extendinglongitudinally thereof and downwardly beneath the same, means .pivotally supporting the plate beneath the cowl, a member rotatablymounted upon the plate, and operating means for the cover connected with said rotatably mounted member and adapted to effect the raising and lowering of-the cover.

8. In an automobile body, a cowl having a ventilating opening, a cover therefor, a plate rigidly secured to the underside of the cover and extending longitudinally thereof and downwardly beneath the same, means for pivot-ally supporting the plate at its opposite ends, beneath the cowl, operating means forthe cover pivotally connected with the plate, and means yieldingly engaging the cover to prevent rattling of the same.

9. In an automobile body, a cowl having a ventilating opening, a cover therefor, a downwardly extending arm rigidly secured to the coverintermediate'its sides, means for pivotally supporting the arm beneath the cowl, a ,member rotatably'mounted upon the arm beneath the pivots thereof, and an operatingrod for the cover having screwthreaded engagement with said member.

' 10. In. an automobile body, a cowl having a ventilating opening, a cover therefor, a plate secured to the cover and extending downwardly beneath the same, said plat-e l'iaving angular end portions, means connected with said end portions for pivotally supporting the plate beneath the cowl, and op'- eratingmeans for the cover pivotally connected with said plate.

11. In an automobile body, a cowl having a ventilating opening, a cover therefor, a downwardly extending plate secured to the cover beneath thp same, said plate having angular end portions formed thereon, means connected with said end portions for p1votally si-ipporting the plate beneath the cowl,

bearings connected with. said plate, a mem-' her having trunnions journaled in said bearings, and means connected with said member for moving the cover to and from closed ponation.

12. In an automobile body, a cowl having a ventilating opening, a cover therefor, a downwardly extending plate beneath the cover having a flange secured thereto, said plate having upturned portions at its ends, means pivotally connecting said upturned portions with said cowl, bearings formed upon said plate, a member l'iaving trunnions journaled in said bearings, and an operating rod for the cover having screw-threaded engagement with said member.

13. In an automobile body, a cowl having a ventilating opening, an instrument board, a cover for said opening,a plate'rigidly secured to the cover and extending longitudinally thereof and downwardly and rearwardly beneath the same, means pivotally supporting the plate beneath the cowl, a member pivoted upon said plate, and an operatingrod havingits outer end extendiigig through and guided by said instrument board and having its inner end threaded into said pivoted-member.

In testimony whereof, I afiix my signature.
